Experimental results and calculations of the Cr/Fe system magnetic order are reported. The role of the interfacial diffusion of Cr in Fe substrate during the Cr growth on Fe(001) is particulary investigated. The magnetic moment distribution is computed in the real-space by means of a self-consistent Hubbard-type tight-binding Hamiltonian. A simulation of the variation of the total sample magnetization during Cr growth shows that the more Cr and Fe are interdiffused at the interface, the more important is the decrease of the magnetization. The effects of this interdiffusion are found to be more important if the growth mode is not layer by layer. The local magnetic moments are strongly affected by this interdiffusion. Experimental studies are explained within this framework. For Fe/Cr/Fe trilayers, experimental evidences of spin-flip in the upper Fe film are shown. Limitations and extensions of the model are discussed.
